ADF7012BRUZ Datasheet PDF - ADI

●The ADF7012 series low power multichannel ISM band FSK/GFSK/OOK/GOOK/ASK UHF Transmitter designed for short-range devices (SRDs). The output power, output channels, deviation frequency and modulation type are programmable by using four, 32-bit registers. The fractional-N PLL and VCO with external inductor enable the user to select any frequency in the 75MHz to 1GHz band. The fast lock times of the fractional-N PLL make the ADF7012 suitable in fast frequency hopping systems. The fine frequency deviations available and PLL phase noise performance facilitates narrow-band operation. In the compensation register, the output can be moved in <1ppm steps so that indirect compensation for frequency error in the crystal reference can be made. A simple 3-wire interface controls the registers. In power-down, the part has a typical quiescent current of <0.1µA.
